I'm interested in using ART1 to cluster line segments, similar to the
examples show in Carpenter and Grossberg (1987), "ART2:
Self-organization of Stable Category Recognition Codes for Analog Input
Patterns."  The authors show a number of examples of clusters generated
by applying different 'vigilance' parameters to line patterns, but don't
elaborate upon the dimensions of shape that they used to define the
patterns.  Does anyone know how they did this?  Also, has anyone out
there implemented ART1?  I would be interested in hearing your
success or (gulp) horror stories.  Thanks.
